The vessel also carries 30mm Automated Small Calibre Guns and Miniguns for use against fast attack craft.
The system is radar-controlled and is said to provide a ‘last chance’ defence for ships against anti-ship missiles and aircraft.
Phalanx automatically detects, tracks and engages threats. It features a 20mm M-61A1cannon, search and track radar and FLIR in the Block 1B model.
To date, the United States Navy and 20 other nations have purchased more than 850 Phalanx systems.
